x i dont think the non gold version will be a bad choice, you wont get the full use of the rail anyway in that length and i dont believe the difference in maneuverability versus carbon in that size will be that noticeable, you could always install a reel if you need it..thats the practical side of it in my view..although the boys with toys logic will say "Go ahead mate Spoil yourself why not
" ...
as for the 82, i think its a good size, what turned me off it personally was that its an odd size so i was a bit worried about the ease of sourcing spare stuff (bands shaft etc..) later down the road.. if you feel the 90 will be much for your viz, go for th 75...
