LBF and OGS

I have been smoking these two blends now for a few months now and I think I'm due to make a comparison (for others to relate).
I find myself wondering if I have a sensitivity to Perique. Here's why I think so; When I smoke LBF for a few days I find my gums will be sensitive to the touch and get a little red. When I smoke OGS, the same thing happens but not to the degree of LBF (don't worry, it's not that serious). I find when I remove the Perique circle in the LBF it makes for a nice smoke with VERY little bitterness from the P. Comparing OGS to LBF without the P in the middle thet are close to each other. I honestly think that leaving LBF to age for a few months helped mellow it out, but the P was still bitter to me.
I want to try out some different Va/VaBur blends. I find my palate to be very selective and I can pick up on little hints of flavors in the tobacco. I enjoy smoking different blends and with me having an open mind of most things I'm willing to try pretty much anything. What would ya'll recommend as some nice Va, or VaBur's?

I thought the centre was perique lol (duh). Oh well still learning. I like it better without it anyway.
When I tried my first round of LBF I smoked 2oz in about a week and a half, some with the centre and some without. I found it to be a little spicy on the tongue but a smooth smoke. The second batch I had come in had alot of bright leaf in it and it wasn't as spicy. I have let it sit 2mo in a vac sealed jar (closed hand tight and boiled for 5min). Maybe the heating did something to the tobacco, IDK, but it tasted nothing like the last batch I got. I might try the 'cooking' method mentioned being done with EF on some OGS tins and see what I get.
I will do an experiment with some LBF tomorrow evening. I will take some and boil it in a jar for 10min and some in another jar for 20min. Seal them for 60d then try them out. Has anyone done this or something simlar?

Thanks cigrmaster! I was looking at MacB's Old Dark Fired (since I like MacB's products)
