Extra raises after first draw in Triple 2-7

Ive been kinda amazed by the play at 5-10 and 10-20.. People are willing to cap after the first draw with their premium (and sometimes not so premium) one card draws. Mostly people do this while in position which i understand somewhat as it may force a break. Often I see people doing this OOP as well which makes no sense at all.. SSII says that with both drawing one it isnt awful for you to have 2347 after first draw and check-check with a considerbly worse 1 draw because at that point the edge is fairly small. I will raise my premium draws HU in position to define my hand a bit and discourage someone from betting into me with rough pat hand after the 2nd draw but other than that I like to wait until i have the goods to put in several raises. I feel like im in the minority here.. What do you guys think
