Personally - I am afraid of climb-cutting. Even though I can do it safely now and understand how and when it can be dangerous. I prefer a double bearing template bit, it allows to flip the work halfway through the router pass, adjust but height and proceed downhill the grain direction without climb cuts.
Whiteside template bit is very expensive, but I view it as essential safety gear. https://www.amazon.com/dp/B009102BMK/ref=cm_sw_r_cp_apa_glt_fabc_WBKEEW2ZZ6FTS16J2ZVT?_encoding=UTF8&psc=1
When I have a spare $150, what I dream of: Whiteside Model UDC9112 Spiral Combination 1/2" SH X 7/8" D X 1-1/8"CL.
