I am thinking of purchasing a Susato whistle in high D. There are several choices on their website. Can someone tell me the differences in the different models; Kildare, Oriole, Dublin, V series or S series? Even though I have been a member of Chiff and Fipple for awhile I am just now starting to actually learn to play. I am a complete beginner. I have over a dozen whistles which include a Susato in Low G, and high D whistles by Burke and Busman. But I am curious about which Susato would be good for someone just learning to play. 
Susato makes good whistles … but some are not for the faint of heart or particularly well suited to beginners, or so some would say.
The Oriole is a brand spanking new design which I have not had the chance to play yet. You can be the first one on your block to own one. 
I have not seen any reviews on one yet.
The Dublin has been the lower priced whistle in the line for years and has a cylindrical bore. At one time they were made from CPVC pipe. They play fine.
The Kildare has a modestly tapered body. They are the meat of the Susato line and I’ve seen more than a few of these in the hands of pro players. They seemed quite popular back in the 90’s. I’d start with a Kildare. They’ve been around long enough that the Chinese seem to have taken a liking to the design recently.
I’ve owned a couple dozen Susatos. Almost all have been Kildares. They have a nice tone, IMO. They are impervious to the elements and quite hardy. The only vulnerable part of the Susato whistle is the edge of the blade. If you are looking at high D whistles they come in two bore sizes - the S and V. The S is one loud whistle and can be really loud in the upper register. It goes all the way up to eleven - one of the loudest whistle out there. The V has a smaller bore and is less “in your face” than the S. It’s not a quiet whistle though. The V series would be more suited to a beginner in my estimation unless you are trying to rid a village of rodents or something like that. Don’t get me wrong the S series Susato is a good whistle but you might find it a bit too much to handle right off the bat. Do look up the “O-ring tweak” though.
I will make an observation. If you already have a Burke and a Busman high D, I don’t think you’d be gaining much with a Susato. You can drop it in the pitcher of beer with no ill effects on the wihstle but that might be it. I’d try not to do that with the other two.

Thanks for the info, feadoggie! You have been very helpful.
I really like Susato Kildares for outdoor use. They break down into a nice size and are not bothered by temperature extremes like so many whistles. Very durable and they don’t sound that loud outdoors. Not too bad in cross winds either. Seems like some professionals like them for the same reasons.
Do take a bit more breath control to sound their best and the O-ring addition does help. C is my favorite key, but D is very nice too. I would not play a standard bore one in small enclosed spaces if you value your hearing. But that’s true of other whistles that tend to be on the high volume side like Reyburns.
I like Susato C whistles, but the Ds are too loud for me, especially in the upper register.
Worry about my hearing. As mentioned above, you already have better whistles
in the Burke.
I would (and do), and doubt I’ll go deaf because of it…

But then I can’t really see any whistle as ‘loud’ in outright terms!
I’ve got permanent ringing in my ears as a result of whistle playing. I was lucky in that my hearing is still normal, but for the tinnitus. When it comes to hearing loss, by the time you become aware of it the damage is done. Plug your ears.
