The road to ELO 2000: ending my time soon with 1.e4

Have been debating for a while now whether I should ditch 1.e4 as my main opening move and forcusing on 1.d4 instead. The reason for this is simple: 1.e4 has just too much theoretical ground work t ocover. I prefer 1.d4 because it can lead me to play 'minor' 1.d4 systems such as the london system, colle sysem, torre attack and tromposky, which offer White plenty of attacking opportunies.

I'll be willing to listen to any comments on this subject. Cheers!
