There are a lot of the T34's that have tillers. I'm not sure that the tiller to wheel is 50/50, but it is really a matter of choice. With the storage space under the cockpit sole and ease of access, many owners have converted easily from tiller to wheel and from wheel back to tiller.
My boat has a wheel which I really like. (after changing up to a larger size) I do think the tiller would provide a better cockpit layout than what you get with the wheel, especially if you want to single hand the boat. The wheel being placed forward in the cockpit does get in the way somewhat. The helmsman can easily reach the genoa winches however my boat has been converted to midboom sheeting that makes it very hard to trim the main from the helm. When racing we place the genoa trimmer behind the helmsman and the main trimmer in front. If we race with just two of us aboard, it gets very difficult climbing back and forth around the wheel.
The original mainsheet configuration had the sheet lead to a SHORT traveler that spanned the space between the cockpit seats right in front of the helm. In this configuration it would be easy for the helmsman to also trim the main, but really limits use of the traveler.
