To be fair to your past as well as the future you should get a 200 mm from each brand and enjoy a balanced approach.
I haven't been looking but have been flat out with the angle grinder shortening some tube extenders in my optical path..what could go wrong?...I thought it was a radical approach but everything seems to have worked ...I only hope it is enough to reach focus.
After taking off a couple mm with the grinder I then used a smoothing file and two small grades of sanding type paper...not a plug and play unit is the RASA.
From what I have seen the 200 mm triplet seems the perfect scope...I will ask Bintel how much.
