I would recommend learning at least a mediocre snake and making sure your pull or kick at least stay above average. Why stay with one shot? The more weapons, the better you'll do. You'll also prolly notice that as your pull or kick shot gets better, it scores even more frequently as the snakers/rollers dominate, just due to the fact that as more and more of them start appearing, there are less and less of the other shots to learn to defend against.
As David Gummeson & T-Mac (06 & 08 Tornado Worlds, 09 Nantes World Cup, ad infinitum), have demonstrated as they cut swaths through the pros and promasters with their pullshots, it really works both ways. If you like pullshots, or whatever, you can always use a half-decent rollover as a "scrubduster" to get through the riffraff and beginners, then just decide when to use your oldschool shot to attack all these rollover whippersnappers.
It should work wonderfully for you, both ways, and if you've had the time and training to get a good shot besides the rollover, then you should take the same hint that all newbies and foosretards have learned, learning and adding a passable snake is easy to incorporate into your game, without the injuries and strains the other shots have always imposed. That's an easy answer, c'mon!! I know from playing with him, that promaster and former world champ Tom Yore from Tampa has a damn good snake, which he only uses in pickups, BUT STAYS WITH HIS WORLDCLASS PULLSHOT in competition.
And please don't be like the herd of purist, bigoted, just plain stupid oldschool players who refused to learn the shot, even if they never used it in pickups or competition, because learning the shot, even by yourself, ALSO TEACHES YOU HOW TO DEFEND IT, AT LEAST THE BASICS LIKE STANDARD POST D. A lot of disillusioned elitist morons disdained even learning the shot by themselves, which prolly triples or quadruples the speed of learning the easy basics of how to block ordinary rollovers, SHUTTING OUT EMBARASSING LOSSES to most beginners, rookies, and most amateur level players. Don't be like a nonpro baseball pitcher who only has one decent pitch, or an amateur hockey player who only has a stroke shot with no useable slapshot or a decent backhand shot.
