Yes I guess 19 is about E1 but, like any new area, you need to make allowances and leave yourself a few grades in hand until you get the hang of it. The rock on TM is fantastic, as Trangia says, but the steepness and exposure is a bit of a shock when you first get on it. That experience of being puzzled as to where the route goes next and, on having the description shouted up again, being convinced you must be in the wrong place because what is being suggested is so obviously impossible at the grade (or any grade) happened to me repeatedly the first year or so I was there!
Easy warm ups might be Arrow Face (11 VDiff-ish, right under the cable station) or something on the lower buttresses (Indian Giver on Venster Buttress on the way up was a popular Severe). Africa Crag (on the buttress left of the cable station) is good too.
Good VS-HVS: Cableway Crag, Atlantic Crag, Escalator.
When I lived there I used to think of Jacob's Ladder as a scenic jugfest useful as a quick way of getting visitors to the top. I did it again last Christmas after (I was disturbed to realise) a 20-year gap with one of my oldest friends with whom I've shared many an ill-advised adventure, although it's probably fair to say that neither of us had done much for 6 months or so. Longer than that if we're honest. Knowing the geography, we decided to do it alpine style with rucksacks so that we didn't have to come back down via Fountain Ledge but could run over to and down Platteklip (you'll see how it works when you get there), in time for sundowners before dinner.
Pretty quickly we decided that we needed to cram one bag into the other so the leader could take it a bit more seriously. It must have had a lot of traffic over the last two decades to reduce the size of the holds so much and I was surprised that in all my earlier ascents I had failed to notice the possibility of falling from the long traverse into space over the roof and ending up in an inconvenient position. The juggy overhanging groove on the first pitch wasn't much fun carrying two rucksacks, either... Anyway, it was all pretty hilarious and was a very memorable day. It's always worth it to have the admiring crowds photographing you as a conquering hero when you climb over the railings at the top.
Don't let this put you off - I really was out of shape and struggled on gritstone VSs when I got back. If in doubt it's probably worth doing a few pullups before you go.
