Impeller choice for 1997 speedster Twin 720

[Mask1]

I am looking at buying new Impellers and wear rings for my boat ..only has 135 hours on the engines ...super confusing ..skat trak site recommends 14.5/22.5 swirls for stock engines and 17/26 super slim for modified ....and Solas on iboats.com recommends Sd-SC-X16/23 .
Does anyone have experience with these impellers .. and what is our experts opinions about these ... to me whole shot is more important than top speed I get 58mph on GPS already with 2 adults as is .
Any advice would be much appreciated.

I've talked to the guys at group k about upgrading my impellers. He recommended their custom-pitched solas concord impellers at $259 each. Harry said these are the best bang for the buck that increase speed and acceleration.

Thanks for the heads up ... just got off the phone with Harry at group k and he said they have done extensive testing on these motors and boats. He does recommend the Solas Concord and said they custom pitch the right and left differently for optimum performance and wear and tear. (might be why my 2 catbon seals were worn so differently)He told me $279 per ....he must like you better....LOL
