10/20, short donk, blah blah line check

[berserk]

Villain is 40/20/1.5 over 300 hands, don't know much about him besides that and that he is not a regular. Also he has 35bb so hes probably a donk.

Folds to villain in SB who raises to $60, Hero calls in BB with A[img]/images/graemlins/club.gif[/img]7[img]/images/graemlins/club.gif[/img]

Villain bets $80, Hero raises to $260 obviously planning to call a shove (which would be $380 more)

Thoughts - unless I plan to fold somewhere in the hand (which certainly could be considered on later streets) then by calling down 3 streets I would be putting in his stack anyways. I'm much more likely to get the money in good/flipping now, hopefully with lots of hands like T[img]/images/graemlins/spade.gif[/img]J[img]/images/graemlins/diamond.gif[/img] or K[img]/images/graemlins/diamond.gif[/img]X. So is this super standard?
