adb_11, "...scrap the idea of making a purchase of RB or rake?...", My guess is yes but take that with a grain of salt. I never used a rake and my experience with the RB was less then stellar...
The length of the top-link is very important for RB, BB or the rake, since you have the BB, learn how to make it work. Also, don't forget that you can angle the BB to the left and right. My neighbor uses a RB and knows how to used it... it works very well for him (and fast, too). He owns a BB but never uses it (and it's not just because it's been at my farm
). I just bought my own BB, a used 6 footer.
