Tier 1 HSMP extension please help

[ramdev0180]

hi every one,
it would be great if some one help me with my present situation
i am in the UK on Tier 1 (general) with HSMP Approval Letter

1. I got HSMP Approval on december 5th 2005
2. EC Stamped January 2006( for an year till Jan 2007)
3. Got 1st Extension in Jan 2007 (for 4 years till jan 2011)
4. Got 2nd Extension in Jan 2011(for 4 years till Jan 2014)
(Applied for 2nd extension with Tier1(general) Extension Application form due to confusion and they have automatically changed my extension to Tier 1 General PBS and stated in their letter along with my passport returned that for the future extensions i need to apply with Tier 1 PBS application form)

Due to staying outside of the uk for longtime i was not eligible for applying for ILR at this time and i have to apply for extension in jan 2014.

My queries:
1. I am i eligible to apply for extension using Flr Tier 1(HSMP) as i can not get enough points if i apply with Tier 1 PBS application form.?

2.If i can apply with Tier 1 (HSMP) form do i need to show maintenance funds balance in my last 3 months account statement as we do for Tier 1 General PBS extension.?

3. Do i need to clearly explain about my situation in my covering letter with Flr tier 1 (HSMP) application.?

4. Is there any possibility for refusing my extension or returning my application ( if i apply for FLR Tier 1HSMP) as my current stay in Uk is Tier1 PBS based on their letter given along with the previous extension.

5. (OR) regardless of my present situation holding HSMP APPROVAL dated 5th Dec 2005(which fall under Judicial review ) i can blindly go ahead and apply for extension with FLR Tier 1 (HSMP)?

please suggest me what to do for my coming extension

please help

thank you
