In a moment of weakness I did that (130mm f/7 triplet APO, very nice for what it was). Barely lasted 4-5 outings before conceding the mak I had at the time (SW 180mm f/15) beat it on the planets easily and was the scope that was used, every time.
Small fast refractors do have a place - wide-field imaging. But as planetary scopes - not good - its all about focal length (6m or more) and razor sharp optics which means significant aperture ... unless you have an observatory big enough for a 7" APO, better off sticking to SCT or maks.
