Right - any expert help would be really appreciated.

I joined Aegean due to great *G threshold (when I still flew less) and decent redemption on *A ex South Africa. Due to my most frequent flights being on SA in discounted economy (TLVW) and Aegean earning only 50% for those buckets, I am wondering if there is a more efficient option. My main consideration is Krisflyer due to 100% earn, but redemptions are hard to puzzle out and have heard some annoying things about award availability. (I do have a CPT - SIN - BKK - CPT in C booked on them so at least that would also be a start to re-earning gold again.)

Question is - do I stick with Miles + Bonus (only have about 24k miles balance now) or should I jump ship somewhere else?

(1) What is your home airport? (SFO, LAX, MCO, etc.) CPT
(2) What types of fares do you usually buy ? (C, F, Y, etc.) C internationally, Y locally (at least 2k miles per week, all SA, mostly TLVW buckets). (F on miles ;-) )
(3) How many miles do you usually fly each year? (<25K, 25k-50k, >50k) 120k
(4) Do you have any kind of status at present? What is it? (UA Silver, M&M Senator etc) EK Silver, A3 Gold
(5) What is most important to you in a FFP? (Frequent upgrades on travel, priority services when flying the airline, good award redemption rates, free lounge access, etc.) Miles earning/redemption and the normal *A perks
(6) Which routes do you fly most often (US Domestic, Transpacific etc) South Africa -> Asia/Europe, and domestic CPT-JNB shuttle
(7) Preferred Airlines SQ, TG, (EK), (CX). SA domestic
(8) Do you travel for work or pleasure? (Can you chooose your airlines, class of service?) Both.
