so you used 6.5%ba it sounds like. 100ml in 2 bottles? i wouldnt put any more BA in. is it painful? you could put some BB in. for 50ml every 1ml will change it 2%. put a little in, heat, and let it settle. if it crashes you can put a little more if you wish, or just heat every so often instead.
next time use 3%ba and 8-10% benzyl benzoate.
