Im about to take on my first self bow, getting my tools and materials gathered now. I'm looking for a good raspto use. From what ive read the ones to get are the Nicholson 49 and 50. Heres the issue, Im kinda strapped for cash dont want to spend $70 on 2 files. If I were to only buy one atm, which would you think would be better, the 49 or the 50, or a different raspall together. Thanks alot for any input.
