Rectifier which one?

Hi!

Just sold my good old 86 VFR and bought a 94 VFR, and i was wondering which is the best replacement rectifier?
I'm going to the isle of man TT this year and does not want to be stopped by a broken rectifier, won't take any chances.
Haven't got the bike yet, so don't know if it still has the OEM rectifier.

And how about the rear shock, is it usable or pure crap like on the 86? Gonna put racetech springs in the front, maybe gold valves later on.

 

I have installed CBRF4I on that vintage with good results, aboot the correct size to fit in required area, cheap and plentiful at local wrecking yards here.
