I've had the same issue bowless, but love the strings.  Have them on 4 of my higher performance bows.

What kinds of draw weights are you guys shooting with skinny strings? And does anybody know what string material SBD uses?

It is all on the SBD site!

Love the strings but would like to see the serving just a little higher. My square goes beyond the serving on top.

I would ask Pierre. If it is possible, he'll be more then happy to do that for you.

I use their 6 strand on a 53#@29.  No problems, very quick.

Is the skinnier string quieter?  And is the serving thicker to fit the nock?

I don't think two strands makes a big difference and I would say the serving is the same size. But I think Pierre will correct me if I am wrong, cause I can sence his presence here....
Personally I get as skinny as I can get with my strings, meaning 6 strands for my bows under the 53 lbs and 8 for above.

If the serving is too short for a bow square, are there problems with having enough room for shooting split finger?

I don't have any problems with a bow square and can't imagine other people have. But, YMMV.

Or you bowsquare appearantly....  

As for split finger: with the nocking point at 9/16, I have enough room for 3 fingers above nocking point and 4 under and my paws ain't exactly small....

The strings are great. No problem with split fingers, three under, etc... Just my bow square goes a little higher than the serving, no big deal.

What do you think of the recurve wraps?  Do they lessen performance, quiet the bow, get heavy when wet?  Do they really make any difference?

For my hunting bow, I'm using a Black Widow PCH recurve. I went the opposite direction and make thicker strings. 20 stands of 452X, .30 halo. Then a second serving of 62s serving above and below the tied on nocks sets. It's easy on the fingers, quiet and rugged.
The .30 halo fits tight on the nock at first but mashes in.
I once read how the nocks should fit really loose on the string. So I was doing that.  It cost me custom recurve from an accidental dry fire. Also I have had strings tear several times. That will mess you up for a while!
So I over build my strings. I see no loss of performance or quietness. If you ever have a dry fire or tear a string you'll consider doing the same.

I've been using a  homemade skinny HP string for years with never a single problem and personally I will NEVER go back to a "normal" string. Have read tons of great feed back on sbd strings and if I didn't make my own that's where I'd buy.

I don't have experience with those, but I am sure Pierre can answer that question.

I also use the SBD strings. I use the 6 strand on my 47# GN Bushbow.    

I use exclusively his 6 & 8 strand SBD strings. They are excellent.

Those who use the SBD strings, do you get the recurve wraps?

Been using 8 strand SBD's on my recurves for a while...I like 'em.Haven't tried the wraps,dpg.

thanks for your input, i started 6 strand with 43lb toelke longbow really shoots great   thanks  stan

The 6 strand scares me. I use the 8 stand on my rigs. I know it is only 2 more strands,but on the other hand it's 2 more strands.    
Pierre makes a great string,to the point it improves your bow. rat'

I use the "recurve wraps" on my recurves and find it definitely quiets the bow even more. One of the bows is a working curve and one is a static tip. Same effect on both. I like 'em.
