Splitting tens

Consider myself a well-read relatively new blackjack player. A couple of times I've experimented a bit splitting two tens against the dealer's 5 or 6. Wong suggests one not do this unless one has a positive mimimum +4 count. However, I've won frequently doing this, often playing basic strategy only. For some reason, this move deeply disturbs other players, some even going so far as to call me greedy or winning with the move or flaunting some basic rule. Not seen this move discussed much in the literature. Anyone have experience/suggestions or better win/lose rates with this move?
