The vino should distil just fine CC. Plus the main thing about brandy is the grapes/fruit in the first place, followed by how you manage it from there i.e. french oak barrels, the amount of time to age etc etc.
The boilovers seem to be connected with the clarity of the wash/wine/whatever i.e. it should be as clear as you can make it before running it in the still. Hence the use (as recommended by the UK importer anyway) of boiling chips of some kind - it doesn't have to be the ceramic beads, or "saddles", it can be small shards of broken glass. Which are a damned sight cheaper

Good on yer though matey, I'm also happy with both my "smart still" (same as the easy still I believe) and my "super reflux 25L" still. Apart from a little mild scalding with the smart still - it didn't burp, it belched and farted at the same time (I was re-distilling an 85% ABV batch that had come out cloudy).
One thing I did learn was that high % alcohol is bloody marvellous for cleaning up the kitchen
