Deboichet SL2 42 vs Tectonics F8

[Tur53]

I do couple races in the Euro Cup and also compete nationally for high slots.

I have pretty much all boards of the I Sonic 2006 line plus 101 from 2007.

For Warp 8.3 sail and I Sonic 125 I have a Tectonics F8 42 cm. I hear from some others that moving to Deboichet SL2 42 would be a big plus. I weigh 85-86 kg (with my west).

My question is: would SL2 indeed bring an significantly improved performance with the above combination or should I keep my tectonics and spend the 200+ Euro on some other size.

Many thanks for your expert opinions.
