I have the SA short 8/9 and throw it on the CND Skagit, a 9 weight rod. The 8/9 short head feels heavier in the air on the forward cast. By that I mean, it is as easy to pick up, form a D loop with and initiate the forward stroke as the Airflo's and windcutters, but it's mass really shows when it's sailing out there, pulling out running line and tugging at the reel at the end of the cast. It feels like a lot of mass over a shorter line without feeling "too heavy". As far as turning over tips, the following comparison is not really fair because of design. The Airflo, windcutter and SA, though similar in weight, are very different tapers and behave much differently. It will depend on what kind of feel you prefer.
The Airflo Delta tips weigh the least (considerably, at approx. 110 grains) and they turn over pretty easily with the Delta body where the short head feels a bit clunky turning over both the airflo tips, the 150 grain Rio tips and T-14, but is does turn that T-14 over where the Airflo does not want to. The real gem on the Skagit is the Windcutter using the compensator. Threw the 8/9/10 this past Sunday with the sink compensator and 150 gr. tips and it lifted from the water easiest and threw the farthest with the least effort, and certainly must have gotten the deepest with 30' of line sinking. I'd like to try the 9/10/11 because it actually felt a bit light, like it was still sort of casting off the tip of the rod and not digging in.
The SA short head actually felt best with the floating tip and sinking poly leader. I use 50# braided loops coated with thinned down Aquaseal to stiffen them without adding bulk. After much trial and error I'm settling on these loops as they do not hinge, are not too hard and flex with the same stiffness as the main line, behaving like the line itself for a more fluid turnover. I mix 3 parts Aquaseal with 1 part Cotol and it is very easy to work with (letting it soak into the braid then brushing off all excess) and sets up quickly, unlike straight Aquaseal.
