I am not an expert in the slightest way, in fact I'm a rank novice as well, but if you read the book and try low bar, the amazing coaches here will give you amazing advice for free. I get where you come from in regards to not wanting to low bar due to no coaching as I have no coaches in my vicinity either, but the advice from this community and their coaches are amazing. So in my very unqualified opinion I feel you can definitely switch to low bar and the amazing coaches will be with every step of the way as they have been with me. Just my 2 cents
