I thought Limits just had 255% hit, period, so what weapon you use is completely irrelevant to a limit missing or not. Could be mistaken granted. 255% Hit is max, however, unlike most FF games, FF7 has 255% Hit just mean you need a little more than 60% evasion for there to be a hit rate below 100% (compared to FF6 or FF8, where in both cases, 255% hit means you'll never miss; Cactuars prove this easily enough. I think FF10 does the same thing, but testing that is a much bigger pain...unless FFX is completely lacking in true Evade Ignoring, and all evade ignoring moves are just tagged 255% Accuracy, which has the same effect in practice and...yeah, I'll shut up <_<; )
That said...
There are ways you CAN manipulate FF7 Accuracy of Limits, namely Fury Status. It kills your accuracy; use that, go find an evasive enemy, use Limit a bunch of times, it'll probably miss eventually (those weirds in Ancient Forest come to mind.)
Blind probably works to, and ideally both could be used, but not sure if its possible for a PC to apply Blind, let alone if Blind is used by any enemy with noteworthy evasion for that matter (all FF7 status but Sadness and Fury are healed after battle.)
