If they are only half as good as everyone says they are then you have to treat yourself to a 50 Tournament Shortstroker by Ian Miller!

One thing is for sure, although I don't know much about standup fishing the heavier line classes, if you want to really fish 80 to the max you need a somewhat different class and style of rod, shorter, with the Wind On Aftco rollers and maybe a short bent butt.  Needless to say you need to really know what you're doing when fishing with gear like that.  Whereas with a heavy 50 I prefer a longer rod about 5' 8" to about 6' or about 6' 2" with a straight butt (easier to tease a fish with) for travelling probably a straight aluminium butt (Aftco or Pacific Bay) - I haven't seen every standup blank out there but I like the Seeker TS-60XH or 55XH blank, I don't like an extreme radical fast taper, more of a medium fast taper with some stiffness in the tip.  You already have/had a rod that you like so that's half the battle, just test rods till you find one that acts similarly.

I can back up the comment on the GUSA blanks bit, the 30-50 blank I have had Pete make for me is pure sex. Of course, have actuallyUSED it yet (mutter mumble mutter), but soon I hope, very soon......

cheers, Stu.
