If it's cheap & it helps.... It doesn't hurt & you're happy (= win/win)The hollow bar is SLIGHTLY better. Obviously if you had a non-F41 and then went to the big hollow tree trunk, then you'd really be able to determine the seat of the pants feel. However, stepping up from 32 to 36 is only 4mm!!! Or approximately a tad over 1/8" in diameter. Think about it. YES. It will likely be a tad better than the F41. NO. It's probably not worth the headache if you're not going to do everything else necessary to make a corner carver out of the car. Again, unless you ALREADY HAVE THE PARTS. Then I say put them on. What the heck?
F41 to the 36mm hollow is kinda like wearing a condom. Is she really going to notice the extra girth because it's a little bit bigger in diameter? Maybe if it's ribbed.
