Unfortunately, saddles are a total crap shoot. What feels good to one person will feel horrible to the next. For the most part, a beginner will want to avoid ultra-light and thinly padded models like the Selle Italia SLR.
In the last 25 years, I've found a lot more saddles that were uncomfortable than comfortable.
I've been using a Fizik Gobi for about five years, but they redesigned it last year. The new Gobi XM is nothing like the old one. Totally ruined it for me. I've managed to find some NOS stock on E-bay, so I won't run out for several years now.
I actually bought an SLR just as an experiment. Although I don't get any sitbone discomfort, it feels like you're sitting on a board. Probably not going to be a keeper, even if it does weigh 145 grams (not the 135 marked on the saddle).
