You can do it! I think getting the hang of DT shifters will help you shift better in general. I found it is best to anticipate any shifting that will be needed, instead of waiting until I hit an incline to downshift. I'll now do it just before and spin easy for the last few meters until I am using the lower gear. One of the best things about going friction is that you now have all the trim you could ever want for you FD. I shift both front and read w/ my right hand.
