I am committed to acquiring an SL+, but am debating if I “need” the cpu. Some reading tells me I can forego the cpu, but I am not sure how easy the setup and day-to-day use would be without it. I currently have a 310xt and was wondering if I can just get by using that? I realize the 310xt won’t be able to display the extra data, but if it displays my watts (and I know my LT zones) what more would I really need?
Any thoughts would be helpful, thanks.
