I have tried on both Prelude and Pilgrim. I personally prefer the Prelude and wasn’t much impressed by the Pilgrim. But first of all, you need to know that both of these harps are high string-tension harps which I would strongly suggest you to try them out first, to see if you feel the tension is ok with yourself. If you live in US, there’re lots of rental programs (eg. rent to own) available, you might want to rent one for a few months before you decide to purchase one. The Prelude feels very much the same as the pedal harps in terms of string spacing, tension and tone quality. L&H makes non-pedal harps with light-tension too, check them out if you are interested. If you are more interested in playing classical music (which I guess you are, since you’ve played the flute. Hey, me too!) and thinking that you will switch to pedal harp eventually, I think prelude is a pretty good choice, or even the L&H Troubadour, which is just 4 string shorter than Prelude, smaller in size and a few hundred dollar less expensive.
