It depends on a lot of factors. If you go into it with no ego and wanting to gain something from the more difficult shot then you should be fine. All of the PBA patterns are playable...you just have to find the right ball with the right layout and surface for your game.
If you guys think that a 50 pin difference is big...I'm not too proud to post this-
Last year THS average- 230
This year THS average- 227
2 years ago summer Sport league- 168
This year 1st time PBA Experience- 185

I actually finished the Sport league in the top 10. I'm middle of the pack average-wise in the PBA league. On a THS last year I was top 5 in average for the city. This year probably top 20. Currently 8th in association All-Star points.
