About vers & int. Verse is multiplying your damage, so the more int you have, the more verse adds! Exact numbers is
here : each 5,34 vers on BG multiplies your damage by 1%. For cool numbers 16 vers is 3.00%. If you roll Dark Iron Dwarf or Mag'Har Orc (or panda with their food) and you'll buff your spellpower to 300+, 16 vers will add 3% of 300 that's 9 addictional int instead of 8 int on fallen aprentice. To be precise 16 vers ~ 8int at 266 spellpower.

MH+OH gives you 6 extra int with enchant, but 12 secondaries instead of 16. If you've got like 270 spellpower then 6 int ~ 12 vers, so MH+OH of the quickblade/aurora with at least 6 summary verse (for ex. MH 2vers 4 crit & OH 4 vers 2 haste) would be better than foamspittle.
