I have studied a number of professionals but have yet to find one that really synergizes with my play style.

I am looking for a player who focuses on good solid territory in the beginning and then due to the safety of their groups is able to viciously attack.

Does this remind you of any professional?

how about a balanced playing style instead?

Myself I wanted (and still want) to develop a style where I built thick positions and then reducing what the opponent thought was his territory, winning in the endgame. The example pro here seemed to be Otake Hideo. From my personal page at SL you can find experiments with "playing like Otake".

(...) But the strange thing is Takagawa not only does not seek to actively utilize thickness to attack his adversary, he seems to avoid a fight. (...) The ultimate result is that Takagawa's thickness envelops his opponent, neutralizing his strength and safely steering the game into the yose. (...) Takagawa's thickness spreads out and gradually takes control of the board; and finally, when the yose comes, that indirect pressure aggressively asserts its presence and assumes control.

Another player fitting this description is Takagawa, I've replayed quite a few of his games and generally got this nice feeling "ah, I (think I) understand what is going on here"

Jeromie, I think I would call that example by Kitani an invasion, not an attack. Because the bottom left White group is not particularly thick, Kitani gets what looks like a reasonable trade. But I still wouldn't call it an attack--it fits more with the idea that if your own territory is very solid, you can invade without worrying so much about it being trashed as a result.
