Is this normal? (kneeskin/chest covering suit)

Hi there, A question for anyone, particularly men (and maybe Wookie in particular?): Do you "notice the water" around the chest of the suit on kneeskin/full body suit? I graduated from college swimming in '03, so I basically missed the LZR/B70/tech suit era. I've never swum in a full body suit -- I've only competed in briefs, jammers, and legskins before. But in preparation for a couple of aquathlons, I bought this Speedo FSII trisuit . (If you can't see the link, it's basically kind of a truncated kneeskin that goes from shoulders to midway down the thighs, and zips in the front. It doesn't have a "pad" for the bike, which is one reason I bought it). I've tried it a couple of times in a pool, and it feels pretty good. I've done some pace 50s, 100s and 200s with a brief on, and then with the suit, and they're usually a little faster with the suit (by maybe 1 second per 50). But I also have this sense that it's making my chest rise higher in the water, and (maybe?) that there's some water moving around. Is that normal? I can't tell if: 1) it's just a new, higher body position that I'm not used to yet, 2) if there's actually water moving around, or if 3) it's just all in my mind. Obviously, the pace times indicate that it's okay, but maybe I'm just subconsciously trying harder because of it, and over 1500 meters the suit might become bothersome or have a negative effect. Any thoughts? I may just stick with the jammer, but then I pretty much wasted this purchase... Thanks for any responses.
