Last season we tried a full-on passing mode which saw us pottering around in mid-table, before tweaking it a little to sometimes play accurate long balls, which was far more effective. In fact, the best Argyle teams I've watched have always been able to mix styles between short and long passing.
A passing style can work at this level, but it's very fragile. If our passing game is slightly off, or if opposition teams figure us out by cutting off supply to the CDM/wing backs, we're in trouble. We need to then look to play accurate long balls, not just hoofing it anywhere, getting the two strikers to make intelligent runs and gain territory that way. At times against Charlton, we did this well.
From an aesthetic point of view, I dont think a successful team that mixes styles is too bad to watch at all. I've watched us when we were cr*p try and play a long ball style and a passing style, and I'd say they were both equally painful to view.
