I just had a run on the SF 680 with the S185 stab and this combo felt good but a little slow, so I put on the HA 850 with the S185 and this stabilizer seemed to give me more pump ability and lowered the stall speed compared to the S210.
Anyone else tried diff combos worh the HA SF series for more glide and pump ?

The S145V2 and S122 are the go to with the smaller SF wings, any bigger ones just feel draggy.

i agree really love the 142 and WANT to love the 122 but damn if it's not the noisiest little vibrating whistler I've ever ridden! it literally hurts my ears!

i tried sanding the TE but i think i made it worse! anybody can help me with some tips to sand the buzz out of this thing please? ????

I switched brands (among other things) because I never managed to get a single North setup to run quietly.
Now the only whistling noise is coming from me - probably just as dissonant but at least I can turn it off :)

that's funny.. I've used them for almost 3 years and NEVER had a whistle until the 122 stab

I negatively shimmed the S185 and it instantly felt less draggy and gave me alot more lift and stability. I want to try a stab with more glide but not loose the lift and early take off that I can also pair with my HA 's. Recommendations pls ??
