I recommend playing the first 8 bars usuing a contant alternating hand technique. That is, play every 1st, 3rd 5th and 7th 16th with the left hand, and every 2nd, 4th, 6th and 8th with the right. This gives you a fabulous martellato sound, and will produce no physical tension.
After that, you have to start using the right hand only for the 16ths. (Well, not really, but arranging things between the hands might be more trouble than it's worth). Anyway, I think your "wiping" techinque is the way to go. My edition recommends 152 to the quarter. For sure nobody is going to be doing any "pecking" at that tempo. I wouldn't attempt to get a martellato effect with your fingers in this passage - you'll just get tense.
Also, don't just stick with the standard repeated note fingering (1234). Rather, explore some other options that might make the section easier. Be creative!
