Are you talking 'old' fused disk 16.5 or the newer 750mc2 stuff? If its the old stuff good luck break out the tdr and be looking for water,the newer stuff seemed to have some problems as well on the upper freqs with suckouts. I havent had a problem with mc2 yet but what little I have is yet to see 750mghz. I do know that mc2 today cost substantially more than p3 does so somebody beleives in it.
