How does that whole Increase Reflexes work with Force and all? You need to get the threshold wit hits, but what is the Force for?
Force=max hits you can get.
Sources, people

A spell's Force limits the number of hits (not net hits) that can be achieved on the Spellcasting Test.
Also, it's important for preventing your spells getting dispelled / disrupted
The dispelling magician makes a Counterspelling + Magic Opposed Test against the spell's Force + caster's Magic (+ Karma spent in the case of quickened spells). Each net hit scored on this test reduces the hits from the original test to cast to spell. If a spell's hits are reduced, any effects the spell applies are also reduced accordingly. If the spell's hits are reduced to 0, the spell immediately ends.
"to cast to spell" is original text, assuming it meant to read "to cast the spell". Yes, it shows up that way in both SR4 & SR4A.
For additional info, check out "Mana Barriers", I don't feel like quoting every bit of it, since the point has been made.
Also, AJ, please man, buy SR4A so I can stop having to cross-reference.
